Problems solved by technology

[0006] However, due to the special source of plant dyes, the prepared dyes contain a certain amount of sugar and pectin. Even through the purification operation, some sugar and pectin will remain in the dye product. This is why plant dyes are different from conventional dyes. A big difference between chemical dyes, sugar and pectin will affect the diffusion of dyes in the dyeing process, and the degree of influence on different types of plant dyes is different, so when using several plant dyes to match the color of the fabric When dyeing, the diffusion of each primary color dye will be affected by sugar and pectin, resulting in different effects of each primary color on the fabric, thus failing to achieve the expected dyeing effect

Embodiment 1

[0027] Get red dye safflower extract, yellow dye gardenia extract, blue dye indigo extract each 4 grams and dissolve in 2ml ethanol respectively, the ethanol solution of 3 kinds of plant dyes obtained is added to deionized water, stir to obtain uniform and control the mass concentration of the total amount of plant dyes in the dye solution to be 2%, and add the Diacid X model that accounts for 12% of the total mass of plant dyes in the aforementioned dye solution. Multi-functional green environmental protection surfactant, at the same time, add potassium hydroxide to the dye solution and stir evenly. After adjusting the pH of the dye solution to 7, immerse the white cotton T-shirt in the dye solution for dyeing.

[0028] The dyeing conditions are controlled as follows: bath ratio 1:20, dyeing temperature 90°C, dyeing time 40 minutes, after dyeing, wash with water and dry to obtain dyed fabric.

Embodiment 2

[0030] Dissolve 5 grams each of the yellow dye gardenia extract and the blue dye indigo extract in 2ml of ethanol, add the obtained ethanol solutions of the two plant dyes to deionized water, stir to obtain a uniform dye solution, and control the plant dyes. The mass concentration of dyestuff total amount in dyeing liquor is 1.8%, and in aforementioned dyeing liquor, add the multifunctional green environmental protection surfactant of the Diacid X model that accounts for 15% of plant dyestuff total mass Co., Ltd. At the same time, potassium hydroxide is added to the dye solution and stirred evenly, after the pH of the dye solution is adjusted to 7, the silk fabric is immersed in the dye solution for dyeing.

[0031] The dyeing conditions are controlled as follows: liquor ratio 1:22, dyeing temperature is 85°C, dyeing time is 40 minutes, after dyeing is finished, it is washed with water and dried to obtain dyed fabric.

Embodiment 3

[0033] The "yellow dye gardenia extract" in Example 2 was replaced with "red dye safflower extract", and the remaining parameters and processes remained unchanged.

Abstract

The invention belongs to the technical field of dyeing of plant dyes, and particularly relates to a color-matching dyeing process based on the plant dyes. A specific additive is added to control a dyeing environment (the pH value of a dyeing liquid), and a fabric is dyed after plant dyes are matched, so that the influence of sugar and pectin retained in natural plant dyes to diffusion of different dyes is avoided, and the problem that the dyeing color is not uniform after multiple dyes are matched is solved. By adopting the color-matching dyeing process provided by the invention, the fabric is very pure in color, excellent in dyeing rate and very good in fastness, and damage of organic chemical dyes to human skin can be avoided.

Description

technical field [0001] The invention belongs to the technical field of plant dye dyeing, and in particular relates to a color matching dyeing process based on plant dyes. Background technique [0002] The basic colors that cannot be decomposed in the color are called primary colors, and the primary colors can be synthesized into other colors. Usually, the three primary colors are red, green, and blue, and the three primary colors can be mixed to produce all colors. [0003] In recent years, with the enhancement of people's awareness of environmental protection, they have gradually realized that chemically synthesized dyes will cause serious damage and destruction to human health and the environment. Plant dyes refer to the use of natural flowers, grasses, trees, stems, leaves, fruits, seeds, bark, and roots to extract pigments as dyes. Plant dyes are non-toxic and harmless, and will not cause any harm to human health; the dyed fabrics are natural in color and shape, and wil...
